Hey everyone, welcome to this lecture, the benefits of control chart. control charts are extremely popular, there are at least four reasons for their popularity. control charts are a proven technique for improving productivity. A successful control chart program will reduce scrap and rework which are the primary productivity killers in any operation. If you reduce scrap and rework, then productivity increases cost decreases and production capacity increases. control charts are effective in defect prevention.
The control chart helps keep the process in control which is consistent with the do it right the first time philosophy. It is never cheaper to sort out good units from bad units later on. Then it is to build it right initially. If you do not have effective process control, you're paying Someone to make a non confirming product. control charts prevent unnecessary process adjustment. The control chart can distinguish between background noise and abnormal variation.
No other device including a human operator is as effective in making this distinction. If process operators adjust the process based on periodic tests unrelated to control chart program, they will often overreact to the background noise and make unneeded adjustments. These unnecessary adjustments can actually result in deterioration of Process Performance. In other words, the control chart is consistent with the if it isn't broken. don't fix it philosophy. control charts provide diagnostic information.
Frequently, the pattern of points on the control chart will contain in information of diagnostic value to an experienced operator or engineer. This information allows the implementation of a change in the process that improves its performance. In a nutshell, control charts are among the most important management control tools. They are as important as cost controls and material controls. Minitab has made it easy to implement control charts in any type of process, as data collection and analysis can be performed on a computer in real time online environment. That brings us to the end of this lecture.
In the next lecture, we will recap this journey of learning to create control charts in Minitab. Thank you for attending. See you in the next one.
